of 1975 (Public Law 94‐163):

– Established the “Energy Conservation Program for

Consumer Products Other Than Automobiles.”

– Subsequent amendments to EPCA gave DOE the

authority to regulate the energy efficiency of

several types of equipment.

– DOE also has authority to classify additional types

of consumer products as covered products.

• Notice of Proposed Determination (76 FR 34914, June

15, 2011):

– DOE preliminarily determined that STBs and

network equipment meet the criteria for a covered

product.

Proposed Definition of STB

Set‐top box means a device combining hardware

components with software programming designe

for the primary purpose of receiving television an

related services from terrestrial, cable, satellite,

broadband, or local networks, providing video

output using at least one direct video connection
16

Definition of Direct Video Connection• DOE proposes to include a definition for direct video 

as any connection type that is one of the following:

– High‐Definition Multimedia Interface (HDMI);

– Component Video;– S‐Video;– Composite Video; or

– Any other video interface that may be used to output video 
17

Definitions of Direct Video Connection Types

Definition of STB: Comparison to CEA‐2043

DOE’s Proposed Definition Draft CEA‐2043’s De

• Specifies ‘primary purpose’ is to receive television

and related services.

• Includes networks for receiving content.

• Specifies video connections.• Specifies that the device contains both hardware

and software as components.

• Does not specify that ‘primary p

then delivered to a 

device, recording de

client.

DOE NOPR Draft CEA‐20
19

Definition of STB: Reason for Proposed Definit• DOE’s proposed definition excludes smartphones an

consoles from scope.

– Primary use of these devices is not to receive and output v

– These devices would potentially be included under CEA’s d

STB.

• DOE’s proposed definition excludes devices that do n

direct video output.

– STB must deliver content to a display device, at minimum.

– These devices would potentially be included under CEA’s d

because delivering video content to display device is option

21

Exclusion of Network Equipment• DOE proposes to exclude network equipment from s

differences in functionality and use compared to STB

• Majority of stakeholders supported exclusion of netw

equipment from scope.
22

Exclusion of Infrastructure Devices• DOE proposes to exclude LNBs, ONTs,

ODUs, and other infrastructure

devices from scope.

– Devices have significant operational

differences from STBs.

– Proposed test procedure is not

representative for infrastructure devices.

• DOE has proposed setup requirements for infrastruc

devices, to test STBs that require use of these device
23

Issues for Discussion

Issue A*:• DOE requests comment on the proposed definition of STBs.

• In particular, DOE requests comment about whether the pro

definition is specific enough to exclude non‐STB devices such 

gaming consoles and smartphones, yet broad enough to cov

traditional STBs and newer boxes.

• DOE also requests comment on the proposed definitions for 

video connection, HDMI, Component Video, S‐Video, and Co

Video.

*Issue 3 in section V.E. of NOPR.
24

Issues for Discussion

Issue B*: DOE requests comment on narrowing the scope of tod

rulemaking to STBs and excluding network equipment.

*Issue 1 in section V.E. of NOPR.

Issue C*: DOE requests comment on narrowing the scope of tod

rulemaking to STBs and excluding infrastructure devices. If stak

support developing a test procedure for LNBs, ONTs, ODUs, or o

infrastructure devices, DOE requests additional information and 

for the test procedure and the standard configuration in which t

devices should be tested.

*Issue 36 in section V.E. of NOPR (reworded on this slide).
25

Basic Model of a STB• Two STB units are the same basic model if they have

– ‘Identical electrical, physical, and functional characteristics

software download and hardware integration.

– Same multi‐streaming and DVR functionality.

DEFINTION OF A BASIC MODEL

Basic model means all units of a given type of covered product 

class thereof) manufactured by one manufacturer, having th

same primary energy source, and which have essentially ident

electrical, physical, and functional (or hydraulic) characteristi

that affect energy consumption, energy efficiency, water

consumption, or water efficiency. (10 CFR Part 430.2).

Issue D*: DOE invites comment on the discussion of basic mode

pertains to the STB rulemaking.

*Issue 4 in section V.E. of NOPR.
26

Manufacturer of a STB• EPCA defines the term “manufacture” as “to manufacture, pro

assemble, or import.” (42 U.S.C. 6291(10))

• Any person that manufactures a device that meets the propose

of a STB would be considered a manufacturer under DOE’s regu

Set‐top box means a device combining hardware

components with software programming designed for the

primary purpose of receiving television and related

services from terrestrial, cable, satellite, broadband, or

33

DVRs with External HDDs• DOE proposes STBs with external HDD are not tested 

with DVR capability.

– Power consumption will vary based on HDD used for testin

– External storage devices generally optional.

– There is no standardized external HDD.

• If DOE tests STBs with external HDDs as DVR STBs, it 

consider:

– Specifying standard storage device to test DVR functionality– Testing STBs with the external HDD that they are shipped w
34

Issues for Discussion

41

Sleep to On Mode Transition Time• DOE proposes 30 second transition time requiremen

full functionality resumes in a timely manner.

• Stakeholder comments indicate resistance to adopt l

modes if recovery time is longer than 1 minute.

– Long wake times are barriers to adoption.

– Negatively impacts user experience.

– If consumers disable sleep mode, test procedure would like

unrepresentative.
42

Issues for Discussion

Issue G*: DOE invites interested parties to comment on the pro

definitions of on, sleep, and off modes of operation of a STB. In 

DOE requests comment, and data, if available, on the proposed

Sleep Mode Power Measurement• DOE proposes two tests to measure power consump

capable of transitioning to sleep mode:

• DOE proposes the time period for each test in sleep 

(TSLEEP) shall be 4 – 8 hours.

– Captures reduced power consumption states if STB powers 

gradually over time.

– 4 to 8 hours is approximately half – to – full over‐night time 

– Draft CEA‐2043 requires entity specifying use of standard t

measurement time.

Issue W*: DOE invites comment on the proposed duration (4 to 

unless network activities prompt a longer time period) over whi

power consumption of the STB shall be measured and averaged

whether this duration should be increased or decreased to bett

represent the STB power consumption in sleep mode.

Issues for Discussion

Issue AF*:• DOE requests comment on the proposed calculation of the A

for determining the annual energy consumption of the STB.

• DOE requests comment on the proposed hour weightings th

developed based on the ENERGY STAR specification or wheth

alternate hour weightings should be considered instead.

*Issue 34 in section V.E. of NOPR.
121

Scaling APD Requirement• DOE is considering alternative weightings that differe

those models that take less than 4 hours to transitio

• Advantage:

– Would differentiate between models that implement trans

APD at different times.

• Disadvantage:

– Scaling of APD may encourage a very short default APD tim

might be intrusive to user experience. This may force cons

off APD completely.
122

Issue AG*: DOE also requests comment on potential methods to 

APD and the advantages and disadvantages of scaling the powe

consumption in APD. Finally, DOE requests comment on potenti

methods to account for a scaling APD value in the AEC metric.
